Using the Multi Unit Spectroscopic Explorer (MUSE), astronomers have performed observations of an old globular cluster known as Messier 15. The observational campaign delivered essential information about stellar kinematics of the central region of this cluster. The results were published February 24 on arXiv.org.

Research reveals stellar kinematics of the galactic disc
By using a sample of 118945 red giant branch (RGB) stars from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) and Gaia, Dr. Wu Yaqian from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) investigated the stellar kinematics of the galactic disc in 7 Source: https://phys.org/news/2021-02-reveals-stellar-kinematics-galactic-disc.html…
Messier 85 has a peculiar globular cluster system, study finds
Astronomers have conducted a study of stellar population and kinematics of globular clusters (GCs) in the galaxy Messier 85, and found that this galaxy hosts a peculiar globular cluster system. The finding is reported in a paper published October 6 on the arXiv pre-print repository. Source: https://phys.org/news/2020-10-messier-peculiar-globular-cluster.html…
A surprising spiral around a planet factory

Close-up view reveals binary proto-stars in the process of assemblage
High-resolution observations of a young star forming system clearly unveil a pair of proto-stars at their earliest stages of evolution deeply embedded within the source IRAS 16293-2422 in the Ophiuchus molecular cloud. The team led by the Max Planck Institute for Extraterrestrial Physics used the ALMA interferometer not only to pin down the source configuration, but also to measure the gas…
Ultra-diffuse galaxy VCC 1287 investigated in detail
Astronomers have probed an ultra-diffuse galaxy (UDG) known as VCC 1287 with the Keck Cosmic Web Imager (KCWI) in order to investigate its nature. The new results provide essential information about the galaxy’s mass and stellar kinematics. The study was presented in a paper published May 6 on arXiv.org.
